I can't even run BIAB standalone alongside Cubase

Are you talking about the standalone Plugin or the main Biab app ?
Did you set Cubase to release the ASIO driver in the background ?
and same if you are using the main Biab app.

I think Adar is working on the new ver 3 Plugin at the moment, that's why it is slow around here, normally he would be right onto it.

If you could use Reaper in trial mode then when all the tracks are made up by the Biab Plugin just drag them out of Reaper into Cubase.
Have you got existing tracks in Cubase you want to add Biab tracks to ?
